Landsat 9 Live Launch Coverage

Jeff Masek, Landsat 9 project scientist at NASA’s Goddard Space Flight Center, participates in the launch broadcast for the Landsat 9 mission on Sept. 27, 2021, at Vandenberg Space Force Base in California. NASA’s Landsat 9 satellite launched on a United Launch Alliance Atlas V 401 rocket from Vandenberg's Space Launch Complex 3 at 2:12 p.m. EDT (11:12 a.m. PDT). The launch is managed by NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida. Landsat 9 will join its sister satellite, Landsat 8, in orbit in collecting images from across the planet every eight days. This calibrated data will continue the Landsat program’s critical role in monitoring the health of Earth and helping people manage essential resources, including crops, irrigation water, and forests. NASA Goddard manages the Landsat 9 mission. Goddard teams also built and tested one of the two instruments on Landsat 9, the Thermal Infrared Sensor 2 (TIRS-2) instrument. TIRS-2 will use thermal imaging to make measurements that can be used to estimate soil moisture and detect the health of plants.
